Universidade Federal do Rio Grande do Norte, Natal, 2023.https://repositorio.ufrn.br/handle/123456789/53642Due to environmental damage and the potential scarcity of fossil fuel-derived sources, the pursuit and study of environmentally friendly fuels from renewable sources have become of great significance. Biofuels can be derived from vegetable oils, animal fats, and even waste oils. A promising source of biofuels is the macaúba, a palm tree that is highly rich in oil from its pulp and almond. To understand the thermal and thermocatalytic conversion process of an oil, it is important to conduct a kinetic study of the reaction and evaluate all parameters obtained through thermogravimetric analysis (TGA), the most commonly used technique for this purpose. This study also allows for the assessment of the catalyst's effectiveness in the entire process by significantly reducing the apparent activation energy throughout the conversion reaction. The kinetic study of macaúba almond oil, in the absence of catalysts and with Fluidized Catalytic Cracking (FCC) catalysts, was carried out using two models with integral methods: Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS). The activation energy (Ea) was determined to be between 129.32 and 150.71 kJ/mol for pure oil. It was observed that there was a greater synergistic effect, as evidenced by the decrease in apparent activation energy values between 113.91 and 127.11 kJ/mol when using a 3:1 ratio of FCC1 catalyst to FCC2 catalyst. The KAS model proved to be the most effective for this study.Attribution-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nd/3.0/br/Óleo vegetalBiocombustíveisEstudo cinéticoCraqueamentoCatalisadorEfeito sinérgicoQuímicabachelorThesis
